Support for optional Displays

An I2C on-board interface on all types of processors allows connecting a various display types showing the operation mode, the temperature, the audio level and a customer defined logo. See the following example for a possible implementation and display content of such a display.


Basic Display


Black and white display with two touch buttons
Color display with four touch buttons

Supported are basic alphanumerik dispays as well as graphical displays with monochrome or color displays including touch function to control the different modes of the Audio Processor. All are available with different resolutions and different sizes.

Please contact AudioChiemgau for available display types, display colors or content customisation.
